Every Stihl chainsaw chain cuts with a specialised component called a cutter, which is made of two parts: the blade, also called the cutter, and the depth gauge. The depth gauge looks like a small hook on the back of the blade and determines how deep the blade cuts into the wood. Both of these components have to be sharpened to precise specifications for the chainsaw to work properly.

  1. 1

    Grip your chainsaw bar in your vice so that the bar rests parallel to the work bench or whatever your vice sits on.

  2. 2

    Insert your round file into your file holder so that the metal bars of the holder surround the side of the round file.

  3. 3

    Observe your chainsaw chain and find a particularly worn-down, blunt cutter. Stand on the same side of this cutter regarding the links of the chain.

  4. 4

    Place your round file in its holder on top of the blade of the cutter. Hold the file parallel to the floor. Note the angled line on the file holder and orient your file so that this line is parallel to the chainsaw bar. Drag your round file over the blade, moving inward to outward only and always keeping the file holder's angled line parallel to the chainsaw bar.

  5. 5

    Move on to the next cutter and alternate the side of the chainsaw bar you're standing on. Repeat the process you used to file the previous cutter for this new one, and continue until all the cutter blades are sharpened.

  6. 6

    Insert the slot of the depth gauge tool over the depth gauge of a cutter. Look closely at whether the tip of the depth gauge rises above the slot. If so, file the tip down with the flat file. Hold the flat file parallel to the work bench and perpendicular to the chainsaw bar as you file.

Tips and warnings

  • Wear gloves while you sharpen your chainsaw because even a dull chainsaw can cut you.
